Peningkatan Kinerja Mesin Press dengan Perhitungan Overall Equipment Effectiveness (OEE) di PT XYZ

Abstract

ALDIANSYAH PUTRA. Peningkatan Kinerja Mesin press dengan perhitungan Overall Equipment Effectiveness (OEE) di PT XYZ. Dibimbing oleh ANTONYA RUMONDANG SINAGA. Mesin press di PT XYZ mengalami penurunan efektivitas dan kegagalan target produksi akibat tingginya angka downtime. Penelitian ini bertujuan mengukur efektivitas mesin menggunakan metode Overall Equipment Effectiveness (OEE), mengidentifikasi faktor penyebabnya, serta merumuskan usulan perbaikan berbasis Total Productive Maintenance (TPM). Data dikumpulkan melalui observasi, wawancara, dan catatan produksi. Selanjutnya, analisis dilakukan melalui perhitungan nilai OEE (availability, performance, quality), dilanjutkan dengan identifikasi kerugian menggunakan six big losses, diagram Pareto, fishbone, dan why-why analysis. Hasil penelitian menunjukkan bahwa downtime menjadi faktor utama rendahnya efektivitas mesin, yang dipengaruhi oleh aspek mesin, metode kerja, material, dan operator. Sebagai solusi, disusun usulan perbaikan berupa penerapan One Point Lesson (OPL), peningkatan autonomous maintenance, pelatihan operator, serta penguatan budaya 5S dan pilar TPM. Usulan ini diharapkan mampu meminimalkan downtime dan meningkatkan produktivitas mesin secara berkelanjutan.

ALDIANSYAH PUTRA. Improving Press Machine Performance through the Calculation of Overall Equipment Effectiveness (OEE) at PT XYZ. Supervised by ANTONYA RUMONDANG SINAGA. The press machines at PT XYZ have experienced reduced effectiveness and a failure to meet production targets due to high levels of downtime. This study aims to measure machine effectiveness using the Overall Equipment Effectiveness (OEE) method, identify contributing factors, and formulate improvement proposals based on Total Productive Maintenance (TPM). Data were collected through observations, interviews, and production records. Subsequently, analysis was conducted by calculating OEE values (availability, performance, and quality) and identifying losses using the "Six Big Losses" framework, Pareto charts, fishbone diagrams, and "Why-Why" analysis. The results indicate that downtime is the primary factor behind the low machine effectiveness, influenced by aspects related to machinery, work methods, materials, and operators. Proposed solutions include implementing One Point Lesson (OPL) programs, enhancing autonomous maintenance, conducting operator training, and strengthening the 5S culture and TPM pillars. These proposals are expected to minimize downtime and sustainably improve machine productivity.
